Flysch is the dramatic, layered limestone and marl coastline between Zumaia and Deba — spectacular for sweeping seascapes, abstract geology close-ups, and long exposures of waves carving the strata. Best at low tide when rock ledges and pools are exposed; sunrise/sunset gives warm side-light and long shadows. Accessible via coastal path and steps at Itzurun beach (limited parking nearby); dress for wind and slippery rocks. No entry fees; respect protected cliffs and local signage.
